Hint: We must know that froth flotation is a process for selective separation of hydrophobic materials from hydrophilic ones.This process finds application in mineral processing, paper recycling and waste-water treatment industries. Further, the development of froth flotation has helped to improve the recovery of valuable minerals, such as copper- and lead-bearing minerals.

Hint: Think about the name of the process, the term froth floatation defines what exactly happens in the process i.e. separation. You will arrive at the answer by inferring the implication of separation. Complete answer: Froth floatation is a process which basically separates all the hydrophilic (water-loving) components of a mixture from the hydrophobic (water-fearing) ones.
